Nozzle Requirements
When installing the 5900S with Parabolic Antenna on a Ø 20" nozzle, the

the radar beam within a 5° angle from the edge of the parabolic reflector to
the lower end of the nozzle.
The 5900S should be installed so that the distance between flange and
product surface exceeds 800 mm. Highest accuracy is obtained for product
levels below this point.
